I am almost certain that the pros around here have tested props ad infinitum and have come to some conclusions. So without letting out any secrets can anyone offer some hard facts on prop efficiency and efficacy. In particular is the APC 20.5 x 14 better that it's carbon clones in performance? And for the venerable 30-10 with a kv of 220 is 20.5 x 14 simply the "sweet spot" or does it depend?


Thanks as always!
